The addition of motor run caps to a power supply does cause a measurable and audible reduction in AC ripple on the power rails.
Channel separation doesn’t seem to be a parameter that is measured In the audio press.
How about the DC-Link capacitors (like TDK / EPCOS)? - low ESR, low self-inductance - They are also metalized PP.
And "Compatible with wide bandgap power semiconductor (SiC, GaN)" HaHa.😎 Compatible with PASS devices they mean.
I'll order some of these, nice square fitting boxes too.
Whatabout round-can B32320I4267K000, - 260 µF @ €25/Mouser, even €15/Farnell?? Doable. Or an xEVCap - B25654A5207K001, 200µF/€25 with extreme low ESR. It is for a vehicel power train, 50A handling capacity . . .. Definitely a match with IXTQ75N10P.

I compared Ducati 80uF motor run caps vs Kemet 210uF DC Links in a classic M2 build. The Ducati caps soundly beat the DC-Link caps to my ears: smooth instead of edgy treble, fuller midrange, more realistic mid-bass and bass. Thanks for the recommendation, Zen Mod.

The Ducatis are available inexpensively via TME (tme.com) in Poland. I paid $9.52 per capacitor with $12.72 shipping last year to Oregon, USA. Part number of the 80uF version: 4.16.10.87.64. TME also sells a convenient mounting kit for the capacitors: DUCATI-SET-M8.

The 80uF caps are tall - make sure they fit in your build. In my 4U Modushop Monoblocks they just fit. But TME has the full range of Ducati motor runs, so shorter ones are available.
 
Benefits of Ducati for USA DIYers:

1) Who can resist Italian capacitors made by a hundred year old company. 🙂

2) Mounting system made for easy and secure placement in Modushop chassis.

3) Cheaper via TME than other motor run caps via Mouser or DigiKey.

4) Known to sound good.
